I currently have:
Parabola (with Openbox) Parabola is Arch with all non-free packages removed or purified to FOSS only. Good for security also.
Arch (with KDE) -- my fallback / used for Wine, since it's already set up
Gentoo with Enlightenment 17 -- I prefer Arch but Gentoo had more up-to-date E17.
EDIT: the Gentoo install is the newest, and my main system. its quite fast, and I will make it much faster when I get some time to tinker.
If I reinstall, it will be Arch with E17, since E17 has good stable releases now.
